Gamers beware: Keeping too tight a grip on the console and furiously pushing the buttons can cause a newly identified skin disorder marked by painful lumps on the palms, Swiss scientists said on Tuesday.

Called "PlayStation palmar hidradentitis" by the scientists, the skin disorder can cause painful lesions on the palms similar to patches found on the soles of children's feet after taking part in heavy physical activity, they said.

"The tight and continuous grasping of the hand-grips together with repeated pushing of the buttons produce minor but continuous trauma to the (palm) surfaces," Vincent Piguet and colleagues at University Hospitals and Medical School of Geneva reported in the British Journal of Dermatology.
